Surat Al-'A`rāf
(The Heights) -
سورة الأعراف

[ Allah ] will say, "Enter among nations which had passed on before you of jinn and mankind into the Fire." Every time a nation enters, it will curse its sister until, when they have all overtaken one another therein, the last of them will say about the first of them "Our Lord, these had misled us, so give them a double punishment of the Fire. He will say, "For each is double, but you do not know."
